For any positive integern, let U(n) be the group of all positive integers less than n and relatively prime to n, under multiplication modulo n. Show the the Groups U(5) and u(10) are isomorphic

2. Relevant equations

3. The attempt at a solution

any 2 cyclic groups of the same size have to be isomorphic.

For the answer to this problem should i do out a caley table for both groups to show they are cyclic? is this enough along with my statement? i guess what im saying is...does the question ask me to prove that 2 cyclic groups of the same size are isomorphic?
